Herbaceous Perennial

Brassica oleracea

ornamental cabbage

This is the wild cabbage plant from which many types of vegetable have been bred - cabbage, sprouts, broccoli, cauliflower, kale, kohlrabi and more. It is a short-lived perennial which looks very similar to other wild brassicas, with evergreen leaves and yellow flowers. It is extremely variable but the lower leaves are large and fleshy, on stalks, often with several leaflets and a wavy or toothed edge, whilst the upper leaves are small, stalkless and narrow. The flowers become long green pods containing dark brown seeds. All parts are edible when young

How to grow

Cultivation

Grow outdoors in fertile but firm, soil that isn't too acidic. This is the wild type of many of our cabbage-type vegetables and it is likely to be this, if you let any of your brassica vegetables run to seed. It is attractive to butterflies and pollen beetles, but take care as it can harbour pests and diseases which on your food crops will be unwelcome.

Propagation

Propagate by seed

Suggested planting locations and garden types
  • Cottage and informal garden
  • Wildlife gardens
Pruning

No pruning required

Pests

May be susceptible to attack by caterpillars when eggs laid by butterflies, hatch and feed. It is very popular food for pigeons and snails, although once plants are established, this damage isn't usually severe. Also, flea beetle can prevent seedlings from thriving.

Diseases

May be susceptible to brassica downy mildew and brassica white blister
